The present investigation is the study of variation in anatomical properties of the wood of the provenances of four different species of Acacia viz. Acacia mangium, A. auriculiformis, A. crassicarpa and A. aulacocarpa. Provenances, bottom to top and pith to periphery variants were statistically significant for most of the anatomical characters studied. Linear relationship between height and anatomical properties at pith, middle and peripheral positions showed significant positive as well as negative relations. From this, it was inferred that A. crassicarpa provenances with favourable wood anatomy parameters offer great potential for being introduced as a pulp wood species in Kerala. Although, A. mangium provenances are having higher rates of biomass production compared to those of other species, most of the anatomical properties are indicative of their suitability as pulp wood species. The stands of trees of the best performing provenances which are having high rates of biomass production have the potential to be made into a seed production area for serving as interim source of seeds. Height wise and radial variation within trees in the anatomical properties could be further exploited for utilising the provenances for specific end uses.
